House number needs changing for my Order

Been waiting for a connection since 20th Dec give or take, my House number was taken down wrong. I placed a message on the support ticket about this. After being given a few dates for connection and them being cancelled due to stuff not matching etc i was given a date of 12/01/2018. No connection, i wait until Saturday lunchtime just in case because i know it can take 24hours to complete. I ring up, after two phone calls totaling 2hours i was notified that these orders kept being placed for next door not our house even though i did notify on the ticket about the wrong address.

After a lovely lady helping me out over the phone, we're now going through the process again from the start but after the phone calls i get an email about the new start but again its got the wrong house number, i again placed a message on the ticket. Is there any chance someone can look at this please? I don't want to have to go through all this again and keep being delayed due to mistakes, and also will i still be able to keep the current connect date? We need a connection asap due to my Fiance needs it for her work.
